Abstract: Provided are an apparatus and a method for allocating resources in a wireless communication system. In particular, the present invention includes the feature of alternately allocating resources for D2D communication and resources for cellular communication, or allocating resources of a D2D link to not be adjacent to each other. In addition, the present invention prevents interference with the cellular communication and interference with other D2D links by allocating a partial area of the resources allocated for the D2D communication to an area for transmitting a D2D uplink symbol to an eNB, or by adding a GP symbol to a partial area of the resources for the D2D communication. Furthermore, in the case of applying a TDD scheme, the present invention prevents interference with symbols for performing the cellular communication by defining a partial section of a special subframe as a section for transmitting the D2D uplink symbol, or by reflecting a time delay of N OFDM symbol durations. Accordingly, the present invention prevents the D2D communication from causing interference.

Abstract: A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information at a User Equipment (UE) in a wireless communication system. The UE determines whether a transmission of a scheduling request is configured in one uplink subframe in which ACK/NACK information for downlink transmissions is to be transmitted, when a Physical Uplink Control Channel (PUCCH) format 3 is configured for a transmission of the ACK/NACK information, and transmits the ACK/NACK information using a PUCCH format 1a/1b and a PUCCH resource. If the transmission of the ACK/NACK information coincides with the one uplink subframe for the transmission of the scheduling request, the UE transmits ACK/NACK information and the scheduling request in the one uplink subframe by using the PUCCH format 1a/1b, when the ACK/NACK information corresponds only to a Physical Downlink Shared Channel (PDSCH) received only on a Primary Cell (PCell).

Abstract: In this disclosure, methods and apparatus for managing interference are disclosed. In one example, the first station receives the first signal from the base station. The first station acquires information on a specific processing scheme of a second station for processing the first signal to be transmitted to a third station at the second station. The first station receives a second signal from the base station while the second station transmits the first signal to the third station. Here, since the first station has knowledge on the first signal and the information on the specific processing scheme, it can manage interference caused by the first signal from the second station.
